Application Glossary

Compiled by Roland Hess

Although most 3D applications share functionality, the terms used to refer to different tools and procedures can vary from program to program. Here you will find several items and procedures in Blender that use names that may not be familiar to you. We've listed them by their more generic names and added a short description and a page number in this book where you can learn more about it.

Also, Blender has an extensive set of importers and exporters to help it fit right into your existing work flow (.3ds, .obj, .lwo, COLLADA, DirectX). Just look at the Import and Export items in the main File menu to see the entire list.

Animation Blocks/Curve Blocks/Tracks: A set of curves for an object or skeleton bones that are grouped together and visualized as a single piece of animation. Blender term "Action" 201

Curves/Animation Curves: The visualization of the interpolation between key frames. Often shown as Bezier curves, but can usually be interpolated in ways as well. Blender term "Ipo Curves" 58, 76

Depth Mapped Shadows/Shadow Maps: Using a pre-calculated depth map to render shadows, as opposed to ray tracing. Blender term: "Buffered Shadows" 268, 275

Deformers: Functions attached to objects that accomplish live effects, such as smoothing, subdivision surfacing, array duplication, Booleans and displacement. Blender term "Mesh Modifiers" 84

Directional/Direct Light: This lamp type casts parallel light rays. Blender term: "Sun Lamp" 264, 274

Graph/Curve Editor: An editing screen that allows you to directly manipulate the animation curves and keys of an object. Blender term: "Ipo Editor" 58

Hair and Fur: Blender term: "Strand Particles" 296, 309

Maps: Some 3D packages refer modules and images that vary colors and settings across materials as "Maps." Blender term: "Textures" 234

Non-linear Animation/Trax Editor/Motion Mixer: An editing screen that allows you to blend different sets of animation data, as well as to see, adjust and freely rearrange blocks of animation data. Blender term "NLA Editor" 140

Null Objects: Used as reference points, placeholders and assistants when building complex animations, these objects do not show up in renders and usually have limited object attributes. Blender term "Empty" 52

Omni/Point Light: This lamp type casts light in all directions at once.
 Blender term: "Lamp" 274

Paint Deform: This is a method of "painting" on a mesh to push and pull faces and vertices along their normals. Several packages have full-blown sculpt modeling interfaces, and this functionality falls under that heading. Blender term: "Sculpting"113

Scripting/Plug-ins: The use of an embedded scripting language and pre-written plug-ins to expand the functionality of the program. Blender uses Python as its embedded scripting language. 360

Shape Animation/Morph Targets/Mesh Targets: The process of causing a mesh to reshape itself into a different form by modeling the different shapes and interpolating between them. Blender term: "Shape Keys" 194, 203

Skeletons: A construction of bones used for character animation. Blender term "Armature" 154

Sky Light/Hemisphere Lamp: This usually refers to the effect seen with lighting that mimics a cloudy day, i.e. no directional light, but general illumination and shading where objects are nearer to each to other. Blender term: "Ambient Occlusion" 271, 277

Soft Selection/Selection Falloff: The ability to transform selected portions of a mesh and have the transformation also affect non-selected vertices (or edges and faces) to create a smoother transformation. Blender term: "Proportional Editing" 89

UVW/Unwrapping: The process of assigning texturing coordinates to faces of a model. Blender term: "UV Unwrapping" 244, 253

Widget: Graphic elements that can be grabbed by the mouse and manipulated on-screen to transform (translate, rotate, scale) objects. Blender term: "Transformation Manipulator" 49

BLENDER OPEN CONTENT LICENSE 

 Terms and Conditions for Copying, Distributing, and Modifying 

 Items other than copying, distributing, and modifying the  Content with which this license was distributed (such as using,  etc.) are outside the scope of this license. 

 1. You may copy and distribute exact replicas of the OpenContent (OC) as you receive it, in any medium, provided that you conspicuously and  appropriately publish on each copy an appropriate copyright notice and  disclaimer of warranty; keep intact all the notices that refer to this  License and to the absence of any warranty; and give any other recipients of the OC a copy of this License along with the OC. You may  at your option charge a fee for the media and/or handling involved in  creating a unique copy of the OC for use offline, you may at your option offer instructional support for the OC in exchange for a fee, or you may at your option offer warranty in exchange for a fee. You may not charge a fee for the OC itself. You may not charge a fee for the sole service of  providing access to and/or use of the OC via a network (e.g. the  Internet), whether it be via the world wide web, FTP, or any other  method. 

 2. You may modify your copy or copies of the OpenContent or any portion  of it, thus forming works based on the Content, and distribute  such modifications or work under the terms of Section 1 above, provided  that you also meet all of these conditions:  

  a) You must cause the modified content to carry prominent notices stating that you changed it, the exact nature and content of the changes, and the date of any change.  

  b) You must cause any work that you distribute or publish, that in whole  or in part contains or is derived from the OC or any part thereof, to be  licensed as a whole at no charge to all third parties under the terms of this License, unless otherwise permitted under applicable Fair Use law. 

  c) The name of the Copyright Holder or contributors to the OC may not be used to endorse or promote products derived from this software without specific prior written permission.

 These requirements apply to the modified work as a whole. If  identifiable sections of that work are not derived from the OC, and can  be reasonably considered independent and separate works in themselves,  then this License, and its terms, do not apply to those sections when  you distribute them as separate works. But when you distribute the same  sections as part of a whole which is a work based on the OC, the  distribution of the whole must be on the terms of this License, whose  permissions for other licensees extend to the entire whole, and thus to  each and every part regardless of who wrote it. Exceptions are made to this requirement to release modified works free of charge under this  license only in compliance with Fair Use law where applicable. 

 3. You are not required to accept this License, since you have not  signed it. However, nothing else grants you permission to copy,  distribute or modify the OC. These actions are prohibited by law if you  do not accept this License. Therefore, by distributing or translating  the OC, or by deriving works herefrom, you indicate your acceptance of  this License to do so, and all its terms and conditions for copying,  distributing or translating the OC.  

 NO WARRANTY 

 4. BECAUSE THE OPENCONTENT (OC) IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE OC, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE OC "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK OF USE OF THE OC IS WITH YOU. SHOULD THE OC PROVE FAULTY, INACCURATE, OR OTHERWISE UNACCEPTABLE  YOU ASSUME THE COST OF ALL NECESSARY REPAIR OR CORRECTION.  

 5. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING  WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MIRROR AND/OR REDISTRIBUTE THE OC AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE OC, EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 

Any trademarked names or terminology (Trax, Motion Mixer, etc.) are belong to their trademark/copyright holders and are used here only as a reference.
